Four men were in court Sunday charged with separate robberies citywide, including one in which a man brandished a "large machete" to snatch a Lombard woman's purse in the Wrigleyville neighborhood early this morning, prosecutors said.

Harmon, 29, and Jackson, who is 17 and lives with his mother, were charged with armed robbery while Spencer, 18, and Curtin, 35, are accused of robbery, prosecutors said.

Harmon, who is on parole for an aggravated unlawful use of a weapon charge, confronted a 24-year-old Lombard woman early this morning in the vestibule of a building in the 3700 block of North Wilton Avenue in Wrigleyville and displayed a "large machete," prosecutors said.

The two struggled and he fled with her purse containing $100 cash, an iPhone and two credit cards, prosecutors said.

A woman who just happened to be arriving home at the Wilton address heard the victim screaming and saw the attack. She began chasing Harmon, of the 700 block of East 60th Street, found the victim's empty purse that Harmon had apparently discarded and returned it to the victim, according to a police report.

Another pedestrian called 911 and after a short chase, police took Harmon into custody at 12:30 a.m. at 3940 N. Sheridan Rd. The victim was not hurt and the machete and her property were recovered, according to the report.

On Friday in the Lakeview East neighborhood, Curtin, of the 500 block of West 14th Place, allegedly approached a 31-year-old man from behind while the victim was walking home at Stratford Place and Broadway, pushed him to the ground and jumped on his back, according to a police report.

During a struggle, Curtin "ripped the pants off the victim," to get the man's wallet before fleeing, prosecutors said. The victim suffered scrapes in the struggle.

Curtin has ten prior felony convictions, prosecutors said. Police said $20 and a credit card were also taken. Police found impressions Curtin's shoes left in the snow to help bring the case, police said.

Prosecutors said Jackson was one of the suspects who hit the victim and took his iPad, a cell phone, at least one credit card and some cash at 7:40 p.m. on Nov. 22 in the 600 block of North Pulaski Road.

The victim was taken to John H. Stroger, Jr. Hospital of Cook County for treatment of an eye and head injury. Jackson was identified in a photo array and in a lineup, prosecutors said. Jackson, of the 600 block of North Monticello Avenue, has no criminal background as an adult, prosecutor said.

A separate attack occurred Saturday on the West Side when Spencer, of the 900 block of North Lawndale Avenue, overpowered a woman who was texting on her iPhone, stole the phone, her credit cards and identification card on a Green Line train at the Garfield Park Conservatory stop, prosecutors said.

Spencer, who was wearing the same green camouflage jacket he wore during the attack, was arrested after a short foot chase. Spencer's defense attorney said he is a senior at the Austin Business and Entrepreneurship Academy and participates in the After School Matters program.
